shared photos out of order

Hello,

I'm a bit frustrated by photo sharing. I went to visit a construction site today and took several photos in quick succession. I want them to be in order/sequence so that they make sense to others looking at them. It seems that photos shared, then downloaded to a PC, get a new, random, filename. Therefore, sorting by filename is no longer the correct order. Also, sorting by date/time doesn't work either, because the date/time stamp does not store seconds. All photos in the same minute are in random order. ARGGGHH!

Am I missing something?
